@Carl Love Thank you for reply. Yes, we can use coeff(..) as well as GetComponents(..) to extract terms from the second form of the L1fh above.

But my question is how we can extract terms from the following expression (without D_x, D_y, and D_L):

PS:

In Python's Sympy package we can simply use ".args" attribute: L1fh.args or L1fh.args[0]

## @Torre Thank you very much....

@Torre Thank you very much.

## merci...

You're right. Thank you.

## merci beaucoup...

Thank you so much.

## merci...

Thanks that works.

## Par exemple.....

For example, please consider the Maple codes below:

Plex:=[x,y,z];
f1:= x*y-z^2+2*x;
f2:=x^3-2*y^2+z;
f3:=x-y+4*z;
Polys:=[f1,f2,f3];
F:=Polys;
with(MTM):
n:=size(Plex,2)-1;

for i from 1 to n do
S||i:=resultant(F[i],F[i+1],Plex[1])
od;

So, the question is how can I implement Matlab's "while" loop in Maple?
